I have observed that while sending mails with a pdf attachment, the size of
the pdf attachment changes when it reaches
the destination.Sometimes(randomly).....i am not able to open the pdf
attachment...gives an error like "error reading the document".
The attachment behaves differently if the destination site is hotmail and
differently if the destination is lycos.
What could be the possible solution to this.Is this a 'hotmail problem'?

This is typically (probably always) a base-64 encoding, meaning that
every 3 bytes are encoded as 4, so your attachment inflates by exactly
33%. (The original file is 75% the size of the encoded attachment.)
% echo 2.8 .75 \* p | dc
2.10
Your detached file should be about 2.1 MB.
